SPECIFICATION forming part of Letters Patent No. 322,851, dated July 21,1885;

Application filed February 9, 1885. (N0 specimens.)

To all whom it may concern:

Be it known that I, WILLIAM'K. Powsns, a citizen of the United States,residing at St. Louis, in the State of Missouri, have invented a new anduseful Oalcimine Composition, of which the following is a specification.

My composition consists of the following ingredients, combined insubstantially the proportions stated, viz: plastic clay or kaolin, onethousand pounds; glue, fifty pounds; bichromate of potassium, one pound.

The clay I have used is found at Cape Gi- I have given the proportion ofglue, supposing the glue to be of good quality. The quality of glue,however,varies considerably, and the proportion of glue in thecomposition would be varied accordingly, a larger proportion of gluebeing required when the glue is of poorer quality.

Any desired coloring material may be added; but the addition ofcoloring-powder calls for an additional proportion of bichromate ofpotash and glue.

I claim- The herein-described composition of matter to be used in makingliquid calcimine, consisting of plastic clay, glue, and bichromate ofpotassium, in proportions substantially as specified.

WILLIAM K. POWERS.
